Equivalent & Substitute Parts Reference: Honeywell 1CPSC3A Snap Action Switch

Part Overview

The Honeywell 1CPSC3A is a snap action switch featuring 4PST (4-pole, single-throw) configuration with 3NC/1NO circuit arrangement. This component is rated for 10A at 600V AC and 250V DC, with IP67 ingress protection suitable for dust-tight and waterproof applications. The 1CPSC3A is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1CPSC3A is determined by strict equivalence across the following critical parameters:

Circuit Configuration: The substitute part must maintain 4PST-3NC/1NO topology to ensure identical switching behavior and contact arrangement.

Electrical Ratings: Current rating of 10A (AC/DC), AC voltage rating of 600V, and DC voltage rating of 250V must be matched or exceeded.

Environmental Specifications: IP67 ingress protection rating and operating temperature range of -40°C to 80°C must be maintained.

Functional Features: Lighted indicator presence and On-Off/Off-On switch function must be preserved.

Compliance Requirements: RoHS compliance and MSL 1 classification must be retained.

Manufacturer Consistency: Parts from Honeywell Sensing and Productivity Solutions within the CPS series are prioritized to ensure design continuity and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The Honeywell 1CPSA3A is the direct equivalent substitute for the obsolete 1CPSC3A. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the CPS series and maintain identical electrical, mechanical, and environmental specifications.

Product Status Consideration: The 1CPSC3A is classified as obsolete, while the 1CPSA3A maintains active product status. This transition ensures continued availability and manufacturer support for new designs and production continuity.

Compliance Alignment: Both parts are RoHS compliant and carry MSL 1 classification, meeting current regulatory requirements and environmental standards.

Supply Chain Availability: The 1CPSA3A is currently in stock with 981 units available, providing immediate procurement capability compared to the limited remaining inventory of the obsolete 1CPSC3A.

Design Integration: Direct parameter equivalence across all specified electrical ratings, circuit configuration, ingress protection, and operating temperature range permits direct substitution without circuit redesign or application modification.

Frequently Asked Questions (FAQ)

Q: Can the 1CPSA3A be used as a direct replacement for the 1CPSC3A in existing applications?

A: Yes. The 1CPSA3A is electrically and mechanically equivalent to the 1CPSC3A across all specified parameters, including circuit configuration (4PST-3NC/1NO), current rating (10A AC/DC), voltage ratings (600V AC / 250V DC), IP67 ingress protection, and operating temperature range (-40°C to 80°C).

Q: What is the primary reason for substitution?

A: The 1CPSC3A is classified as obsolete. The 1CPSA3A is the active equivalent from Honeywell Sensing and Productivity Solutions, ensuring continued supply chain access and manufacturer support.

Q: Are there any differences in packaging or mounting between these parts?

A: Packaging information is not provided in the available specifications for either part. Consult Honeywell technical documentation or contact the manufacturer for detailed mechanical drawings and mounting specifications.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the 1CPSC3A and 1CPSA3A are RoHS compliant and carry MSL 1 (Unlimited) classification, meeting current environmental and moisture sensitivity standards.

Q: What is the lighted indicator feature?

A: The lighted indicator is a visual feedback feature integrated into the switch design. Specific indicator specifications (color, voltage, current consumption) are not detailed in the provided parameters. Refer to manufacturer datasheets for indicator operational details.

Q: Is the 1CPSA3A available for immediate procurement?

A: Yes. The 1CPSA3A is in active product status with 981 units currently in stock, providing immediate availability for new orders and production requirements.
